Well, another week has gone by and I still don't have a working 520ST. It has been in repair since January 16th. Would you believe that I sent the computer and power supply together along with a note stating the power supply was blown and they only fixed the computer. They sent me back a fixed (?) 520 and the same blown power supply. Thank goodness I checked the power supply before plugging it into the computer. I now have to send back the power supply and they will send back a new one. Note, I MUST send mine back first even though I was told the old black one will be replaced (supposedly they have a design problem that causes +5 to go to +15V). Therefore I assume it will take another week to get another supply, assuming they are available. A word of advise. I have been told that if you have the old black "brick" power supply for the 520ST (P/N CO70099-3) you can be in the same situation as me. There is a design problem that can cause the +5 volt supply to provide +15 volts. This extra voltage does not make the computer work three times faster (3 X 5 = 15). It puts you in the same position I am in. Your computer will have to take a trip to the local repair shop for an extended vacation, hopefully not > 2 months as in my case. The advise I've been given is to get ATARI to replace your old power supply with the newer model. Supposedly the old supply is a disaster waiting to happen. Again, let me emphasize I am repeating what I was told. This is not my opinion and do not claim originality for these claims.

***** Nobody knows the lines I've eaten - song title ***** It's about time I make another comment on the jolly black power supplies. A couple of days ago, my TOS ROM(s) blew. I deduced this from the fact that all went well with the old chips replaced. It took a week for the new chips to stop working. But I gather that these ROMs are really Eproms which happen to be opaque, which makes them somewhat vulnerable to the dreaded power supply surge. Now the people who told me about the power supply scandal have consequently informed me that a very simple test will determine whether the power supply is of the evil variety, without having to wait for disaster to visit. It seems that with zero load, a humble voltmeter will demonstrate the true nature of the thing. So this would indicate that the same fault that causes sub-optimal start-up characteristics also causes inappropriate response to zero load. If so, this would help prevent a lot of indecision about what to do with "the black power supplies".

***** The lines that ate Paris - film title ***** I've just been shopping around for world ST prices, and these are the results: In Australia, the standard B/W system that costs some $700 or so here, costs A$2150 x .704 = US$1510. And the government only takes 20%. Someone is making a big profit over there! But then I suppose some sort of voltage conversion has to be made. In Germany, the cost is DM2898 x .444 = US$1285 for the 1 Meg system with German keyboard and TOS on disk (still!), and the double sided disk drive. That's the 520ST+ that has been mentioned here before. But in Germany now, it seems they have a 1040STS or something, with a built-in double-sided floppy for DM3298 x .444 = US1465. And these two are also just the B/W system. The good news for anyone going to these exotic places is that according to the Atari person who answered the phone in CA, the American version will run on 50Hz with a transformer, but that the keyboard clock will run at 5/6 speed!!! Doesn't this suggest that some crucial part of the keyboard circuit can be replaced with a German part to make it run at the speed? It's very clear to me now that the best policy is to buy here and use a transformer overseas. Can anyone say whether STs have got beyond the US, Canada, UK, Germany Australia and Switzerland? The Bios listing suggests a French version, but that could conceivably have gone only to Quebec. Perhaps the English language component of TOS will be rejected by the Ministry of Culture. And what is this new French computer language coming out soon? I've seen a sample of French Basic. If anyone has a copy of French Basic for the ST I would gladly know about it. ...................ak.

This French version of the Bios (looking carefully at it) actually uses an AZERTY keyboard -- same logic as with QWERTY, those are the first letters in the top row. This keyboard layout is not used in Quebec, or in French Canada for that matter, we use a bilingual QWERTY keyboard. This presents an interesting problem as this latter keyboard possesses a dead key -- you type a ` or a ^ and the carriage (or cursor) does not advance, allowing you to overstrike with the letter you want accented. This is fine for typewriters, but is a ****&&*** for computers. The difference between the AZERTY keyboard and the bilingual QWERTY actually delayed the introduction of a French ST in Quebec. (Should be available by now, I haven't checked.) About French Basic; with a 'decent' BASIC, they only thing needed to "frenchise" it is to change the token lookup tables. I haven't looked at the internals of STBasic but I presume it can be done in a similar fashion. My experience is that it is not worth the trouble -- you learn a few odd words (odd for non-anglophones), and you're ready to go. This is nothing compared to learning a human language. You get used to seeing bilingual code -- variables and comments in French, the keywords in English. It also helps to identity the parts of your code that got borrowed from the net. -- Je'ro^me M.

The ST ikbd (intelligent keyboard) microcontroller derives its timing information from the crystal clock, not the power line frequency, so it will be the same world-wide. I should point out that the ST power supply only provides DC voltages to ST power connector... so the ST's keyboard would not know what the power line frequency was.
